Secondary graphics card not being recognised.

Question

I just got my laptop back from being repaired, and it seems that, after freshly installing arch, the secondary GPU is not being recognised. I have used lspci and xrandr --listproviders and have come up with only the integrated card. Currently I am running on a samsung series 7 chronos 15.6 inch with the HD intel integrated chipset and a second  Raedon HD6490M. Any ideas? Thank you for any help you can give, and I hope my formatting was alright. I am new to the forum.

Answer 1

I went back earlier today and tryed looking into my BIOS and came up with nothing. There, oddly enough, is no setting to enable or disable, or even set some sort of graphics card. I have; however, looked into the problem a bit more and by luck found that others with the same laptop had a sort of similar problem on windows, and they used the SWupdate tool to fix it. I am going to try sometime soon to make a small partition and install windows, and hopefully update the BIOS.
